PACKING FOR JOURNAL BEARINGS.

The present invention relates to im rovements in the art of lubrication, an more particularly the lubrication of hot bearings, for example, the overheated bearings of railroad car trucks, commonly known as hot boxes. It will be fully understood from the following description, illustrated by the accompanylng drawing, in which a section of a railway car truckjournal box in which the invention may be practiced is illustrated.

In accordance with the present invention, the lubricant em loyed for the bearing is distributed to it by means ofa filling having as a base metallic fiber or wool, for example, steel wool, Monel wool, copper wool,

or the like. The metallic wool or fiber 1s thorou hly saturated with the lubricant to be use which may be, for example, a cylinder oil, and is inserted in the journal box in the manner hitherto customary in the use of the usual filling or packing waste which is largely wool. Additional lubricant may be supplied as required. The metallic wool or fiber distributes the lubricant evenly upon the bearing and can withstand high temperatures, such as those occurring in a hot box, without impairing its efliciency, and without igniting, asis the case with the customar packing or filling.

It has een found that the capillarity and distributing qualities of t e metallic wool or fiber and the adherenceof oil thereto can be materially improved by forming upon the surfaces of the particles or fibers a thin film or coating, of the nature of a sulfide. This film or coating of sulfide upon the metallic wool may suitably be provided by immersing the steel wool in a bath ofhydrogen sulfide solution or solution of an alkali metal sulfide or preferably by heating the steel wool or other metallic wool in a fat or oil with which 5 to 25% of sulfur has previously beencombined-by heating to a temperature of 430 or higher, as described in my co-pending application Serial No. 542,493, filed of even date here with. r The, metallic wool is preferably immersed in an" oil-sulfur lubricant of the character therein described and'heated for the formation of the sulfide film;

' The metallic wool, preferably coated with I I a sulfide film, may be used to replace the filling or packing in journal boxes in ordinary operation, or maybe used, if desired,

the metallic wool as a fillin Application filed March 9, 1922. Serial N'o. 542,492.

onlyv for emergency operation in the case of hot boxes and thelike. In the latter case it is preferably used with a special lubricant having a relatively high viscosity at the high temperatures then prevailing in the 'ournal box, for example, the linseed oil-sul r lubricant described in my copending application above referred to. The metallic, wool either with or without the sulfide coating may likewise be mixed with packing waste of the type ordinarily used as a filling or packing and materially increases the resiliency of the packing and prevents clogging.

In the accompanying drawing, the use of or packing is illustrated in connection with a standard construction of journal box. The numeral 1 indicates a journal of a truck, the numeral 2 the bearing of the usual bearing metal and the numeral 3 the-key for holding it in dposition in the box 4. The usual lid 5 an dust guard 6 are provided. The metallic wool 7 which may be sulfide coated, if desired, provides a filling for the lower portion of the journal box and is saturated with the lubricant to be used before it is inserted in the box, additional lubricant bein afterwards added.
